' To .012 wlwmit may concern:

Be it known that I, JOHN FRANCIS WHITE,

subject of the King of Great Britain, re-

sidin in Bradford in the county. of York and ingdom of ling-land, have invented certain new and use 1 Improvements in Textile-Fiber-Drying Machines, of which,

the following is a specification.

. The present invention relates to 1mprove ments in drying. machines suitable for use with textile fiber more particularly when in the form of yarn. a

According to this invention a drying stream-of air is led in under'the yarn at a number of points, distributed over the drying chamber so that the drying air rises up through the lattice or the like trays, supporting it. v I

In textile fiber drying machines it is usual to use heated air, so that its natural tendency to rise will assist the maintenance of the direction of flow upwards through the fiber. Outlet flues will preferably be provided having damper or the like control means.

Air is led into the machine under the tray or lattice of succeeding vertical rows to escape from the machine thro h the aforementioned flues. The inlet pipes or ducts are connected to a conduit on the outside of the dryer, which leads from a heater such for instance as of the type comprising 'a nest of steam pipes in a chamber, t e air stream being propelled therethrough by a fan.

-The invention will be more particularly described with reference to'the accompanyin drawings in which:

igure 1 is a-partly. sectional side elevation showing one form of drying arrangewith a supply of heating steam which may be the waste steam fromv some industrial process. The heated air; then passes along a main trunk 4, completelyalong one side of a drying apparatus 5,'suitable for acting on textile fiber.

This ty of. machine is particularly suitable for t e drying oftextile fiber when in the form of hanks of yarn but the invention is obviously applicable to other types of. textile drying machine.

The volume of air entering the machine is preferably maintained substantially constant at the various points by suitably modifying the sizeof the inlet conduit 4, along the machine as shown. This conduit has side assages 6 leading into the chamber 5 and h beneath a tray or lattice 10 formed with as openings 7, 8, 9, at various levels perforations 10' and carrying the fiber to a be dried.

It will be noted particularly that the heated inlet air stream is entering at the bottom of the chamber and moves upward through the material on the lattice 10.

In order to control the flow of heated air at suitable places outlets 11, 12, are provided, to rovide for a temporary or the like control means 13 so that the flow of air can be definitely regulated and short circuiting of the air stream within the dryer avoided.

To further improve the efliciency of the apparatus as a whole, it is preferred to take in the air for the supply to the fan'or blower 1, from the cooling chamber 14, into which the hanks of textile yarn or the like are assed by the lattice 10 after having been ried in the chamber 5. These hanks will come in at the top of the machine" as shown.

It is also desirable that the air inlet to the chamber 14 should be at the top of the chamber, preferably through slots 14' arranged in the roof this air passing down as shown by the arrows to an inlet pipe 15, for the fan 1. This inlet conduit 15 may be controlled by a valve 16 so that inlet from the chamber 14 can be cut off'when desired and the air'supply for the fan 1 then taken fromthe atmosphere through conduit 17 or from any other desired apparatus.

' By the above arrangement the advantage is obtained not only that heat is absorbed .from th cooling chamber to increase the -thermal efliciency of the plant as a 'whole as less heat will obviously be demanded of the heater for the air subsequent to the'fan, I

but further hot humid air will no longer be projected intothe room in which the cooling machine or chamber is situated as hitherto as the air is now drawn from this room and down through the fiber to the fan. I declare that what I claim is; .1. A textile fiber drying means, comprisw ing means to impel an air stream, means to heat said stream, a closed chamber, means to pass fiber to be dried through said chamber in horizontal planes a number of times, a hot air flue having its first outlet adjacent the inlet of the fiber to the chamber and its final outlet at a higher level adjacent the outlet of the fiber from the chamber.

2. A textile fiber drying machine comprising in combination means to impel an air stream, means to heat said air stream, a closed chamber, a hot air flue vertically disposed in said chamber tapering gradually towards the top outlet on said flue at varying levels vertically along it, and means to pass fiber to be dried horizontally above the outlet.

3. A textile fiber drying machine comprising a closed chamber, means to pass fiber to be dried horizontally through said chamber from the bottom progressively to the top, means to pass heated air through said fiber vertically upwards from the bottom to the top, a cooling chamber adjacent to said first chamber, means to pass the fiber from said first chamber to said cooling chamber, means to pass said fiber in said cooling chamber horizontally across the chamber progressively from the top to the bottom and means to pass cool air from the bottom to the top of said chamber through said fiber.

In Witness whereof, I have hereunto signed my name this 3rd day of April 1922, in the presence of two subscribing witnesses.

- JOHN FRANCIS WHITE.
